Basic Modeling Rules

Modeling Rules		Example
The plate thickness must be uniform.
Model the inner radius (R) of a bend to be 0 or more and the plate thickness or less. Model the outer radius (R) to be [inner radius R] + [plate thickness]. *Automatic quotation is not possible for models with non-uniform thickness. The model modification function can be used to fix these models and may allow automatic quotation. For more information, please click here.
Bending inner radius should be 10mm (.254″) or more, and bending outer radius should be inner radius + plate thickness. For the range of bending radius, please refer to the “Range of Bending Radius“.

Hole Identification Specifications

After CAD data is uploaded to meviy, it is internally converted into a neutral file format. During this conversion, the hole type information (tapped hole, countersunk hole, etc.) is lost.
As a default hole recognition setting, hole diameter and shape features are detected and compared to the hole information database to infer the hole information that will be carried over to the meviy platform.

However, SOLIDWORKS users can use a new function that allows you to change user settings to directly transfer original hole information from CAD data to meviy.

Tapped Hole Identification and Selectable Sizes

Inch Thickness Gauge Standard

Tapped Hole Identification

Hole diameter information in meviy’s hole information database is registered corresponding to the nominal diameters of tapped holes from each uploadable file extension. Detected hole diameters are checked against the table below (Table 1).
*If the detected diameter does not match any entry in the table, the hole will be treated as a through hole. However, you can change the hole type or nominal diameter when configuring the quote settings.
*If a diameter corresponds to multiple nominal diameters (below, 5.00 mm), the larger nominal diameter (M6) will be prioritized and selected.

Tapped Hole Identification

Hole diameter information in meviy’s hole information database is registered corresponding to the nominal diameters of tapped holes from each uploadable file extension. Detected hole diameters are checked against the table below (Table 1).
*If the detected diameter does not match any entry in the table, the hole will be treated as a through hole. However, you can change the hole type or nominal diameter when configuring the quote settings.
*If a diameter corresponds to multiple nominal diameters (below, 5.00 mm), the larger nominal diameter (M6) will be prioritized and selected.

Friction Drilled/Tapped Holes Modeling and Sizes

Inch Thickness Gauge Standard

Friction Drilled Tapping is not applicable for Inch Thickness Sheetmetal

Metric Thickness Gauge Standard

Friction Drilled Tapping Holes Modeling Rules

When a cylindrical flange shape element is detected, it will be identified as a friction drilled/tapped hole.

Modeling Rules	Example
The inner diameter (d) should follow the same rules as for Tapped Hole Identification described above. Model the flange height (h) and thickness (t) to be less than or equal to the Sheet Thickness.

Friction Drilled/Tapped Hole Size Selection

Friction drilled/tapped holes cannot be selected for perforated metals, shim plate materials (Cold Rolled Low Carbon Steel (for Shims) or 304 Stainless Steel (H) (for Shims)) or clear resin.

Countersink Modeling and Selectable Sizes

Modeling Rules for Countersunk Holes

When a conical shape element is detected, it will be identified as a countersink.

Modeling Rules	Example
Model the angle of the conical shape to be 90°. The ratio between the outer hole diameter (D) and inner hole diameter (d) must be as follows: If d ≤ 4.0 mm, the ratio must be above 1.4, If d > 4.0 mm, the ratio must be above 1.7.

Countersunk Hole Identification

The countersunk hole is recognized through two steps below.

STEP1

The pilot hole diameters for countersunk holes for each CAD package are registered in the meviy hole information database. Detected hole diameters will be checked against this during modeling (see table below).

*1 Pilot hole diameter for Siemens PLM-NX JIS model
*2 Pilot hole diameter for Siemens PLM-NX ISO model

STEP2

Once the countersunk hole is recognized according to the aforementioned modeling rules, the nominal diameter is determined according to the pilot hole diameter range. (Table below)
If the detected hole diameter does not match any of the entries on the list of pilot hole diameters, the hole is treated as a through hole (or tapped hole).

However, you can change the hole type or hole diameter when configuring the quote settings.

Countersunk diameter	Pilot hole(d) range	Example
M3	3.2≦d≦4.0

Modeling Rules for Keyhole Type Holes

When a keyhole shaped element is detected, it will be identified as a keyhole type hole.

Modeling Rules	Example
Model the keyhole type hole to meet all of the following conditional expressions: d1 ≥ 4.5mm (.177″) d2 ≥ (2 x d1)+2mm(.079″) h>0

Hanging holes for Plating / Painting

For plating / painting, the product is hung and immersed in treatment baths.
If the model does not have holes already, be sure to add through holes near the corners or end face of the part.
*Model the holes so that they are approximately ø4 to ø5.2 mm (.157 – .205″).
*For models with a length of 420mm (16.535″) or greater, or for models with a weight that exceeds 8 kg (17.6Lb.), add at least 2 holes to the model.

Depending on the size and shape of the part, you may need to add more holes or change the hanging holes.
You will be contacted if this is the case.

*1 The hole may be deformed if it is below the minimum value.

The dimensions are therefore inaccurate, but will be processed as they are.

*2 If the distance is under the minimum value, re-tapping will be necessary and the fit may be affected.

*1 When a is not secured by the slit’s horizontal width, or when there is an acute angle bend, we can still provide an estimate, but instead of the limit value c, the aforementioned “Minimum distance between the hole and the bend” will be the limit value for the hole position.
*2 If the slit’s height is smaller than b or the outside R (fillet size) of the bend, automatic quotation is not possible.
*3 The limit value c is uniformly 3.0 mm only when the nearby hole in the right figure is a burring tap.

Modeling Rules for Perforated Metal

Modeling Rules	Example
When requesting a quote for perforated metal parts, model the part using either no holes or only through holes (mounting holes). If the number of through holes exceeds a certain number, automatic quotation may not be possible. (There is no need to model the staggered/lattice-like hole patterns characteristic of perforated metals.)

Bending Conditions

Bending Interference

For sheet metal parts, the meviy platform performs interference analysis for the bending process.
The forming will be deemed impossible if the results of the analysis suggest there will be interference with the die.

Example 1) Model image before and after bending during normal conditions

曲げ加工の干渉

Example 2) Model image where die interference occurs

Bending interference

If a warning message is displayed, check the part for any interference using “Check the interference image” and consider changing the shape.
After taking corrective action, re-upload the 3D model and check the revised quotation results.
The design guidelines for C-bends and stepped bends (Z-bends) are provided below as more detailed examples. See below.

Design Guidelines for C-Bends and Stepped Bends (Z-Bends)

To prevent die interference, design models with reference to the standard shapes shown below.

Modeling Rules	Example
When outer dimension A is less than or equal to outer dimension C, set inner dimension B so that it is greater than A. Outer dimensions A and C must be at least the minimum bending height (See machining limits: minimum bending height, mentioned above)
The stepped bend height should be equal to dimension A plus double the plate thickness (t). Dimension A must be equal to or greater than the minimum bending height (See machining limits: minimum bending height, mentioned above).

However, the meviy platform determines whether it is possible to manufacture the model based upon positive results of the interference analysis. (Examples given below)

Example 3) C-shaped bending interference:　Adjust the size of the channel web in order to clear any interference (the figure on the right shows the analysis image).

Presence of Edges Parallel to the Bend Line

Any backgauges used in the bending process, along with the edges of parts, are taken into consideration in the interference analysis of the bending process. The angle of the part during the bending process may not be stable if there are no edges parallel to the bend line, creating a risk that the bend may not be made in the correct position. If the below message is displayed, consider changing the shape such that the model includes edges parallel to the bend line.

Example 1) No edges parallel to the bend line

Minimum distance between cutout and bend

The bending process is carried out by placing the workpiece (to be bent) on a die and punching it from above.
However, if the shape of the workpiece does not align on both ends of the die, it cannot be bent.

Description automatically generated

For the minimum distance between the cutout and the bend, we recommend the following.
Please note that if the value falls below the minimum value, the bending line may shift because part of the workpiece is no longer covered by the bending die.
The dimensions will be inaccurate, but will be processed as they are.
In the case of a part that falls below the limit value, it may not be possible to process it. In this case, we will contact you.

Modelling rules	Location
For plate thickness t, the limit value of h should be as follows h = 5t when 0.8 ≦ t ≦ 2.0mm (.031″ ≦ t ≦ .079″) h = 4t when 2.3 ≦ t ≦ 9.0mm (.091″ ≦ t ≦ .354″)
For plate thickness t, the minimum and limit values of b should be as follows b = t when 0.8 ≦ t ≦2.0 (.031″ ≦ t ≦ .079″), guaranteed value = 2t b = 2t when 2.3 ≦ t ≦ 9.0 (.091″ ≦ t ≦ .354″), guaranteed value = none

Confirmation of nut interference during bending

In the interference analysis during bending, the analysis is performed with the 3D shape of the nut reproduced for the part where the nut can be mounted.
If interference with the die is found as a result of the analysis, the area will be judged that the nut cannot be attached.

Sheet metal parts Quoting Error Troubleshooting

Edge Breaking Finish Notes

There is a possibility of minor scratches on appearance surfaces from the double-sided deburring machine used to eliminate burrs.
Edge breaking and engraving cannot both be specified on the same model. The edge breaking process can cause the engraving to fade.
Transparent resin parts will have the edge breaking finish as standard.

About Hairline Direction

304 Stainless Steel(Single-sided hairline finish) has a hairline finish on the main appearance surface. (See the figure on the right)
The polishing direction of the hairline finish is called the “hairline direction,” and in the meviy sheet metal service, the longitudinal direction of the unfolded drawing created by expanding the 3D model shape is used as the hairline direction.
If you would like to use a different direction, please contact meviy support for a quote.

Logic to determine the longitudinal direction of the development

Calculates the maximum rectangle of the unfolded drawing, and develops horizontally in the direction of the longest side of the rectangle.

Effects on unfolded dimension calculation

Shape with arbitrary hairline direction

In some cases, the maximum rectangle of the unfolded drawing is not defined, or the longest side of the rectangle cannot be defined (See the figure on the right.). For such shapes, the hairline direction is optional, and you can specify the desired direction in the quotation in meviy support.

Shape with arbitrary hairline direction

Effects on unfolded dimension calculation

The effect of expansion due to bending must be taken into account when calculating the unfolded dimensions for manufacturing.
In the case of 304 Stainless Steel(single-sided hairline), the expansion is about twice the thickness of the plate at each bending point, so the unfolded dimensions become shorter by that amount. As a result, please note that the longitudinal direction in the 3D model and the unfolded drawing may be switched. (See the figure on the right)

Effects on unfolded dimension calculation

About pre-finished sheets

5052 AL alloy (anodized clear/black) pre-finished materials can be processed. (See the figure on the right.)

Cut surfaces will not have a surface finish.

If surface treatment is required on the cut surfaces, select a material that is not pre-finished and specify anodizing as the surface treatment.

	Low Carbon Steel (Cold Rolled)
	Cold-rolled steel sheet for use in general type pressing. Characterized by its high dimensional accuracy and attractive surface finish. The standard plate thickness is generally between 0.2 mm and 3.2 mm.
		1018 Carbon Steel (Hot Rolled)
		This is a typical rolled steel for general structural use. It has high strength and is used in a wide range of applications such as construction and machinery. The surface is covered with a black oxide film and is also called black film material.

	Cold Rolled Low Carbon Steel (Galvanized)
	Also used in building materials and has high corrosion resistance. Because this material has been pre-machined with a surface treatment, the cut surfaces will not be plated. However, this does afford faster delivery times. The surface is the color of silver.
	304 Stainless Steel (2B)
	The most common type of stainless steel. Provides excellent corrosion resistance, toughness, ductility, machinability and weldability. Used in a wide range of applications. The surface has a slightly glossed finish.

	304 Stainless Steel (Single-sided hairline finish)
	This is a surface finishing material characterized by long, continuous, hair-like polished grains. The surface is low-gloss to create a relaxed atmosphere. When shipped, a protective sheet (one side only) is attached.
	430 Stainless Steel (2B)
	A common type of ferritic stainless steel. Has a glossier surface finish than 304 Stainless Steel and is characterized by its magnetic properties.

	6061 Aluminum Alloy
	Popular aluminum alloy with excellent corrosion resistance, used in many industries and applications.
	5052 AL Alloy Pre-Finish, Clear Anodize
	5052 AL alloy pre-finished anodized sheet. Cut surfaces are not anodized.Due to the characteristics of the material, there is a possibility the surface treatment may peel at bends.The surface is silver.
	Low Carbon Steel (Hot Rolled)
	Hot-rolled soft steel sheet for general use and deep drawing. The standard plate thickness is generally 1.2 mm or more. The material is commonly used in products with medium plate thicknesses.

	Cold Rolled Low Carbon Steel (Electrolytic Zinc Plating)
	A plated steel sheet with good corrosion resistance. The cut surfaces will not be plated. Because of the properties of the material, there may be some marks on the surface. The surface is gray.
	304 Stainless Steel（No.1）
	After hot rolling and heat treatment, it is acid washed to remove black film and dirt from the surface. It features a matte, satin-finish surface.

	304 Stainless Steel (Single-Sided #400-Grit Polished)
	A material with a highly attractive surface finish commonly used for exterior covers. The surface has a mirror-like glossed finish onto which a small amount of polishing marks may remain. Protective sheets (one-side only) are affixed prior to shipment.
	304 Stainless Steel (Single-sided #4 Brushed)
	Common among polished stainless steels. Used in a wide range of applications.

	Perforated Metal – 60° Staggered Round Hole Type – (304 Stainless Steel-BA, Bright Annealed)
	Perforated steel plates used in a wide range of applications, including in ventilation covers and filters. The material is straightened prior to shipment, but some warping may remain due to the properties of the material.
	5052 Aluminum Alloy
	The most versatile aluminum alloy. Offers excellent corrosion resistance and weldability and is used in a wide range of applications.

	5052 AL Alloy Pre-Finish, Black Anodize
	5052 AL alloy pre-finished anodized sheet. Cut surfaces are not anodized.Due to the characteristics of the material, there is a possibility the surface treatment may peel at bends.The surface is black.

	Electroless Nickel Plating
	A plating finish widely used in industrial applications. Highly corrosion and abrasion resistant. Often used for precision equipment parts as the film thickness tends to be uniform. The color of the surface is white silver.
	Black Oxide
	A plating finish commonly known as "blackening." Often used for precision equipment parts as the film is thin and dimensional changes are minimal. However, care must be taken as parts will rust quickly if the oil runs out.
	Trivalent Chromate (Clear)
	An environmentally friendly trivalent chromate plating finish. Provides excellent corrosion resistance and an attractive finish with a pale appearance.

	Trivalent Chromate (Black)
	An environmentally friendly trivalent chromate plating finish. Gives a black surface finish and good corrosion resistance.
	Clear Anodize
	A plating finish with good corrosion and abrasion resistance. The surface will have the color of aluminum.

	Black Anodize
	A plating finish with good corrosion and abrasion resistance. Gives a black surface finish.
